Vedclass · Answer

(D) Temperature is defined as a measure of the average kinetic energy of the particles in a substance.Since kinetic energy is directly related to the velocity of particles $(KE = \frac{1}{2}mv^2)$,temperature serves as a measure of the average velocity of molecular movement.As the temperature increases,the average velocity of the molecules increases.

Molecules are always moving. Some molecules move faster than others; . . . . . . is a measure of their average velocity of movement.
